Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Initialize standards-based agent configuration across agent harnesses

Readme

Buddy Agent Harness

CI Codecov npm License

An agent plugin and CLI for initializing or updating a consumer repository's standards-based agent configuration across agent harnesses.

Install the plugin

In Claude Code, add the cyberplace marketplace and install the plugin and its init-buddy-agent-harness skill:

/plugin marketplace add cyberuni/cyberplace
/plugin install buddy-agent-harness@cyberplace

CLI

init runs behind the init-buddy-agent-harness skill, which sorts the configuration you already wrote before the command links anything. Install the package alongside repobuddy to mount every command on buddy, as buddy agent-harness doctor, buddy agent-harness init, and buddy agent-harness dep-plugins.

The repository root's AGENTS.md and .agents/ tree are canonical: .agents/AGENTS.md holds shared behavior, .agents/skills/**/SKILL.md holds capabilities, and separately named files hold tool settings. The active harness is enabled by default; explicit user preferences add others. The command preserves user-authored configuration and projects only supported mappings; it records nothing on disk.

init takes --root, --copy, --force, and --format; --help lists them.

doctor is the read-only counterpart, and the one command worth running without any of the above. It reports whether the bridges init created still resolve after a clone — the common failure being a Windows checkout with core.symlinks=false, where git writes a committed symlink out as a regular file and the harness silently loads no skills:

npx -y buddy-agent-harness doctor

dep-plugins derives a marketplace catalog for plugins shipped by this repository's own dependencies, so a harness can install them — reaching a whole plugin (agents, commands, hooks, MCP servers) rather than only its skills:

npx -y buddy-agent-harness dep-plugins

It writes the catalog, then reports what each detected harness needs to match it and the command that does it. It never touches harness state itself. Claude Code and Codex install from this catalog; Copilot CLI rejects an npm marketplace source, and Cursor exposes no plugin subcommand from a terminal.

It never repairs anything and always exits 0; each finding names the init command that fixes it.
